BOAT ED Study Guide with Verified Solutions
Port
Left side of vessel
Bow
Front of a vessel
Hull
Body of a vessel
Gunwale
Upper edge of vessel's side
Starboard
Right side of a vessel
Cleat
Metal fitting on which a rope can be fastened
Propeller
Rotates and powers a boat forward or backward
Displacement Hulls
Boats with displacement hulls move through the water by pushing the water aside and are
designed to cut through the water with very little propulsion
Planing Hulls
,Boats with planing hulls are designed to rise up and glide on top of the water when enough
power is supplied. These boats may operate like displacement hulls when at rest of at slow
speeds but climb toward the surface of the water as they move faster
Length overall
Length of the hull excluding any attachments, this dictates the equipment the vessel must have to
comply with federal and state laws
Transom
Vertical surface at the back of the hull
Tiller
Lever used to turn a rudder to steer a boat
Rudder
A rear vertical stabilizer that controls side-to-side or yawing motion of the aircraft nose.
Outboards
-have more power per pound of weight then do inboard engines
-an outboard is a portable, self-contained package of an engine, gear case and propeller that is
attached to the transom of a boat
-steering of outboard boats is controlled by a tiller or steering wheel that swivels the entire
engine to direct propeller thrust
Inboards
, -have automotive engines adapted to operate in marine environments
-the engine turns on a drive shaft that runs through the bottom of the hull and is attached to the
propeller at the other end
Stern Drives
-have quieter and more fuel efficient engines
-are also known as inboard/outboards (I/Os) because they combine features found on both
inboard and outboard engines. Stern drives are four-stroke automotive engines adapted for
marine use and are mounted inside the boat.
-steering of stern-drive boats is controlled by the outdrive, which swivels like an outboard engine
to direct propeller thrust
Jet drives
Jet drives propel a vessel by forcing a jet of water out the back of the vessel. Directing this jet of
water steers the vessel.
-Jet drives use an engine to power a strong water pump, which sucks up water and then forces
the water out the back to thrust the vessel forward
Impeller
Device used to pump and force water under pressure through a steering nozzle at the rear of the
vessel
Sheets
Lines (ropes) used to control the angle of the sails to the wind
Halyards
